The Carbon-Silicon Micro-Dynamic Filter Bed is a new generation of ecological filter bed system, assembled with nano carbon-silicon as the framework and a micro-dynamic circulation system as the core. It utilizes the triple synergistic effects of physics, chemistry, and biology within the composite ecosystem of ecological grids, plants, substrates, and microorganisms. Through processes such as water storage, filtration, adsorption, release, sedimentation, ion exchange, plant uptake, and microbial decomposition, it achieves efficient purification of wastewater. Simultaneously, by promoting biogeochemical cycles of nutrients and water, it encourages the growth of green plants, realizing the resource recovery and harmless treatment of wastewater. As raw water flows through this system, various pollutants undergo separation or transformation through multiple mechanisms including microbial conversion, bacterial decomposition, oxidation, reduction, absorption, volatilization, transpiration, and sedimentation, ultimately forming an online filtration system characterized by ecological beauty and clear water quality.
